I'm a huge Ron/Hermione and Luna/Everyone shipper, obviously this isn't Romione so I can't that I love it. Though I do think they have some sort of chemistry. This passage is from the Order of the Phoenix book.
"And that complete cow Pansy Parkinson," said Hermione viciously.
"How she got to be a prefect when she's thicker than a concussed troll..."
"Who's Hufflepuff?" Harry asked.
"Ernie Macmillan and Hannah Abbott," said Ron thickly.
"And Anthony Goldstein and Padma Patil for Ravenclaw," said Hermione.
"You went to the Yule Ball with Padma Patil," said a vague voice.
Everyone turned to look at Luna Lovegood, who was gazing unblinkingly at Ron over the top of The Quibbler. He swallowed his mouthful of Frog.
"Yeah, I know I did," he said, looking mildly surprised.
"She didn't enjoy it very much," Luna informed him. "She doesn't think you treated her very well, because you wouldn't dance with her. I don't think I'd have minded," she added thoughtfully, "I don't like dancing very much."
She retreated behind The Quibbler again. Ron stared at the cover with his mouth hanging open for a few seconds, then looked around at Ginny for some kind of explanation, but Ginny had stuffed her knuckles in her mouth to stop herself giggling. Ron shook his head, bemused, then checked his watch.
Luna said she wouldn't have minded if Ron went to the Yule Ball with her. Maybe she had a crush on him.
Then this:
"I'll make Goyle do lines, it'll kill him, he hates writing," said Ron happily. He lowered his voice to Goyle's low grunt and, screwing up his face in a look of pained concentration, mimed writing in midair. "I... must... not... look... like... a... baboon's... backside."
Everyone laughed, but nobody laughed harder than Luna Lovegood. She let out a scream of mirth that caused Hedwig to wake up and flap her wings indignantly and Crookshanks to leap up into the luggage rack, hissing. Luna laughed so hard her magazine slipped out of her grasp, slid down her legs and on to the floor.
"That was funny!"
Her prominent eyes swam with tears as she gasped for breath, staring at Ron. Utterly nonplussed, he looked around at the others, who were now laughing at the expression on Ron's face and at the ludicrously prolonged laughter of Luna Lovegood, who was rocking backwards and forwards, clutching her sides.
"Are you taking the mickey?" said Ron, frowning at her.
"Baboon's... backside!" she choked, holding her ribs.
Everyone else was watching Luna laughing, but Harry glancing at the magazine on the floor, noticed something that made him dive for it. Upside-down it had been hard to tell what the picture on the front was, but Harry now realized it was a fairly bad cartoon of Cornelius Fudge; Harry only recognized him because of the lime-green bowler hat. One of Fudge's hands was clenched around a bag of gold; the other hand was throttling a goblin. The cartoon was captioned: How Far Will Fudge Go to Gain Gringotts?
Luna laughed wayyy too hard at Ron's joke.
A short time later:
"Can I have a look at this?" Harry asked Luna eagerly.
She nodded, still gazing at Ron, breathless with laughter.
So I guess Luna liked Ron but moved on as soon as she knew that Ron likes Hermione. I still like Romione more!
